' it known that l, Wannnazq B. Kenton,

a citizen of United States, residing; at

mileage inthe eeunty of Cool: and State of Illlinois have invented a certain new and useful Improvement in Storaelanlrs, of which the follcwing is a specification.

invention relates to filling and venting pipes ror storage tanks-+mere especially for the slnrege ef gasolene and inflammable fluids, safe and convenient handling of which ccncerrs every use: and is demanded it is the general abject of myinvention to provide a simple, cheap construction, capahis of meeting tie snggestien of the above requirements. I

lain fully an are that there is ncthing new l the use of lock nuts themselves nor in the u oi? a lock nut upon a pipe, but i do claim as new-the simple arrangement of two pipes, mechanically and securely connected togetlier which when locked cannot be taken apart, or disconnected from the tank with an ordinary mechanical tool, and when open or closed, are simultaneously opened or closed.

It accomplish my illustrated in the in. which Figure l a side elevation of my complete apparatus. 52 is a fragmentary sectional view longitudinally through the center of the main and vent pipes and closure in position thereon. Fig. 3 is a sectional view looking from beneath on the line 3-3, Fig. 2. Fig. l is a plan view of thebasc plate drawn to a slightly reduced scale. 7

Similar numerals refer to similar parts throughout the several views.

The tank 1 under ordinary circumstances will be located about three 13%1. under ground, and may be of any desired dimensions. Rising from it to an extent sufficient to project somewhat above the surface of the ground are two pipes 2 and 3,'the' pipe 2 being the receiving pipe and referablv hav ing a largerdiarneter than tie vent pipe 3. It is desirable that the main pipe enter a few inches below the top of the tank While the vent pipe terminates at or near the top of the tank. Pipe 1 extends from a point near the bottom of the tank up through the top and oil to any desired point.

l l l and anally the upper Similarly it is desirable that the vent serial in. 577,328.

i ipes '2 and 3 are threaded at their upper ends for a distance just suilici'ent to accliminociate first, the lower .leclr nuts '2 and 5 re spect i vely the base plate 5 above said nuts.

specti 'elgn Said base late, which is shown seg'iarately in plan in rig. is so ionized as to encircle both of said pipe. but by prefen ence daes not actually engage the tluiearis thereof, being" .loese eneugh to slip over the pipes without contacting or damaging the threads. When the parts assembled the plate rests upon the lock nuts and ii and is rigidly held in position by the upper lock nuts 7 and 8. It is clear that when the upper screwed tight all of the parts mentioned will be very rigidly held together, and that furthermore the lower nuts cannot be backed down nor the plate lowered.

Preferably the plate projects beyond. the edges of the nuts in order to support gas kets 9 and 10 which are arranged concentric with the pip-es 2 and 3 respectively, and surround the nuts 7 and 8 respectively.

Fitting over the upper ends of the pipes is 1i which rest. upon the gaskets 9 and 10 respectively, as best shown in F In outline the cover is similar to the base plate but is of slightly smalls dimensions. it will. he noted that the top of said cover is smooth and lock nuts 7 and a re 11 cover 11 Whichis provided with two downn'ardly pro ecting annular flanges 11 and that it lies horizontal when in use, in con sequence whereof it tends to shed water.

Furthermore, the depending flanges 11" cover the parts within and act as a. further protection against the weather.

A stud 12 is rigidly-secured to the base plate as to come substantially midway between the-pipes 2 and 3, and extends upward through a suitable aperture the cover. By preference the upper portion of the stud is rectangular, being shouldered to rest u pon the base plate. At a point just above the top of the cover when the parts are as sembled the stud is apertured to receive the how 13 of a padlock 14, which serves to prevent the removal of'the cover by an unauthorized person.

Itis desirable. that the main pipe be provided with a gauze 16 for straining the oil as itenters and preventing grit and forsign substance from getting into the tank.

pipe 3 be provided with a gauze l7.

in operation, thebese letefizenieins ermsnenfly in place, hel thereby the ock nuts above and below it. a When the cover isin position all that is necessary to re- ;move it is to remove the padlock from the stud 12. and lifi jhe cover ofi. The act of lifting the cover .will not only open the main pipe but will simultaneously open the "vent pipe. This is important because if by inadverhe uc'e or. ignorance an attempt be made to pour the oil into the main pipe when the vent is closed, the air confined H1 ihefianl will ordinerihy stop the flow in the main pipe after a moment and will resuit in the spilling of oil upon the ground and surrounding objects with consequent danger of fire. With the vent automatically open when the main pipeis o n, spilling from this cause cannot occur. "urthermore, with my construct-ion .in which a single cover serves for both pi es, the apparatus may be completely lockc by merely securing a single part of the eppzirotusi With thesiud taken apart by any ordmsry tools.

riveted inplace, as shown, and the threads on the pipes only long enough to receive the plate and nuts, the apparatus cannot be Furthermore the flanges on the cover prevent it from being rotated out of place. Conseted if desired.

2. in a storage oufmit for gasolene and the like, the combination of a tank, a pipe the liquid may be drawn fronrihe tank, e'filler pipe and vent pipe, both screwing into said tank and screw threaded near the top, said filler and vent pipes being adjacent to each other, lock nuts screwed onto said filler and vent'pipes near the top thereof, a plate epertured to accommodate said pipes and resting upon said lock nuts, other lock nuts screwing onto said filler and vent pipes over said plate to hold the latter fast, a cover supported by said plateand chambered on the underside to fit over the upper means for locking said cover to said plate.
